Embodiment Construction

[0059] figure 1 and 2 An example of a loudspeaker arrangement according to some embodiments of the invention is illustrated. figure 1 illustrates a cross-sectional view while the figure 2 Front view is illustrated.

[0060] The loudspeaker arrangement comprises a first low frequency (acoustic) transducer 101, which is a low frequency loudspeaker in the particular example. The loudspeaker arrangement also comprises a second low frequency (acoustic) transducer 103, which is likewise a low frequency loudspeaker in the particular example. Additionally, the loudspeaker arrangement comprises a high frequency (acoustic) transducer 105, which in the particular example is a high frequency and high efficiency tweeter. In this system, the sound transducers 101 , 103 , 105 are mounted in a housing 107 .

[0061] In this example the first low frequency transducer 101 and the second low frequency transducer 103 are substantially the same transducer. In particular, they may be transdu...

Abstract

In a speaker arrangement, a first sound transducer (101) reproduces sound in a lower frequency range and has a first on-axis direction (109). A second sound transducer (103) reproduces sound in the lower frequency range and has a second on-axis direction (111). A third sound transducer (103) reproduces sound in a higher frequency range and has a third on-axis direction (113). The third sound transducer (105) is positioned between the first sound transducer (101) and the second sound transducer (103). Furthermore, a first angle between the first on-axis direction (109) and the second on-axis direction (111) is between 20° and 120°; and a second angle between the first on-axis direction (109) and the third on- axis direction (111) is less than the first angle. The arrangement may render sound with a wide sound stage and may provide a good approximation to a point source.

Description

technical field [0001] The present invention relates to loudspeaker devices, and in particular, but not exclusively, to loudspeakers for approximate point source audio reproduction. Background technique [0002] Audio reproduction from electrical signals is ubiquitous in today's society. The key operation for reproduction of sound to occur is the conversion from electrical to acoustic signals performed by acoustic transducers. [0003] For many audio applications, an ideal acoustic radiator is characterized as a dimensionless, full-bandwidth, omnidirectional pulsating sphere, also known as a "point source". However, it is practically impossible to provide such acoustic radiation characteristics, and trying to approach such ideal acoustic generation has proven difficult and challenging because these requirements tend to conflict. For example, very small speakers (i.e., near-sizeless speakers) have difficulty moving the large amounts of air needed to reproduce bass frequenci...
